If there's one thing we know for sure about procrastination, it's that everybody does it. But perhaps understanding the intrinsic urge can help you to control it a little bit better. 

A video from YouTube channel AsapSCIENCE sheds some light on the psychology of procrastination. In short, your tendency to put off important tasks has a lot to do with the brain's reward system. 

Outcomes that seem relatively far off are percieved to be less rewarding than the immediate outcome of, say, checking Facebook. Plus each time you play a quick game, message a friend or browse a website, you'll likely be inclined to do it again. 

"Every time something enjoyable happens, you get a dose of dopamine, which modifies the neurons in your brain, making you more likely to repeat the behavior," according to the video.  

The entire short video is extremely informative -- especially the last half, which provides some great tips on how to get back to work
